Yeah, need a little more time for everything to stabilize and really see how the activity split between the two chains and how it plays with time.
It will be really interesting to follow.
But if the development only continues on Hive (and it seems it will be the case), it won't be a surprise to see activity on Steem decline while Hive's increase.
I think some of the people doing statistics posts will do some Steem/Hive statistics and comparisons.
